Effect of enzymatic pretreatment of various lignocellulosic substrates on production of phenolic compounds and biomethane potential.
Bioresour. Technol. 192 , 696-702, (2015) Pretreatment of lignocellulosic biomass is necessary to enhance the hydrolysis, which is the rate-limiting step in biogas production. Laccase and versatile peroxidase are enzymes known to degrade lignin. Therefore, the impact of enzymatic pretreatment was stu... |

The importance of chain length for the polyphosphate enhancement of acidic potassium permanganate chemiluminescence.
Anal. Chim. Acta 842 , 35-41, (2014) Sodium polyphosphate is commonly used to enhance chemiluminescence reactions with acidic potassium permanganate through a dual enhancement mechanism, but commercially available polyphosphates vary greatly in composition. We have examined the influence of poly... |
